Because each gate has two inputs and it has four gates inside, it’s usually called a Quad 2-Input NOR Gate.. A NOR gate combines the functionality of OR and NOT gates. The IC 74LS27 is smaller in size and it has a much faster speed which makes it reliable in every kind of device. A-572, Block 7 Gulistan-e-Johar, Karachi, Sindh 75290. The 74LS25 is a TTL (Transistor to Transistor Logic) which uses low power Shottky transistors to reduce the stored charge and get higher switching speeds than with conventional bipolar transistors. 74LS02 is a 14 PIN IC as shown in the pinout diagram. Your email address will not be published. The Strobe input forces the output of the NOR gate to go high when the strobe is low. 74LS27 IC is a member of the 74XXYY IC series.
